PRESSURE-GAUGE VALVE DEVIL Application filed July 2,

Be it known that a citizen of the United States, and resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new anduseful Improvements in Pressure-Gauge Valve Devices, of which the :following is a specification.

The tire vvalve'and'gauge device of the an improved arrangement and construction designedA particularly for use in pneumatic tires attached type and ywhich will have important features and advantages over valve gauge constructions, as

As a result the important commercial advantage obtainsthat the-improved valve deviceV may be readily applied tothe existing valve stems of standard'form y during use and'may be attached to the valve stems of the 'renewed rinner tubes as occasion requires. My improved structure is further special features of,

will be more fully understood by reference to the accompanying drruvings wherein like reference numerals are applied to the corresponding' parts in the several views.'

` Referring to the drawings:

Fig. 1- is a view in side elevation illustrating a valve gauge d evice embodying the features of my invention applied to a valve sleeve or stem of standard form.

Fig. 2 is a similar view showing the partsA in altered position ,as wouldoccur under the actionl of a given air pressure.

Fig. 3 is an enlarged central and'vertical sectional view and Fig. 4 is an enlargedjdetail view-.partiallyI iv in se ctionand partial-lv in elevation 'illus- 'v trating the signal .band features-' A' In theapproved embodiment ofthe features ofthc'present invention, as illustrated, l indicates the valve sleeve or stem of tubu lar form having a central longitudinal lb olrei--f therethrough andprovided at its upper orv outward end with a reduced threaded. ex-A tension 3 and a tapered 'shoulder portion 4.

The sleeve indicated, 1s of substantially uni versally used form and of standard dimensions as employed in'the tmotive" inl dustr The uppe'rportion thereof is interior y threaded at 5 ordinarily to receiye the usual valve insert and the. threaded portion 3 and is ot' standard gauge and diameter to receive the standard size of pump. couplings and valve caps in .the-man ner Well understood. My improved valve j and gauge device is constructed as a unitary j attachment adapted tobe reand separable ceived upon and-secured by the threaded enextension 3 of the attachment thereto throughout the' period;V

of use of theinner tube to which thevalveV sleeve is attached and accordingly 'provides nally threaded h for securing engagement withl the .threads of the 'valve sleeve shoulrises a tubularsecuring-member 6 inter.

es f

der extension 3.-'. The securingmember 6 'has integrally formed therewith an annular flange 7 formed -a't itsunderside with an annular recess 8 forming a. seat'for a packing washer positioned therein to engage the shoulder 4 of the valve sleeve so as to provide an air seal. The, securing member 6 4is extfrnally threaded at 10 to receive there- .onan' internally threaded and inwardly directe annular shoulder 11 of a tubular stationary indicatonemember 12. 4Telescopieally fitted --within the stationary indicator member 12 there istlprovided a movable indicator member 13 'of tubular form having its 15 upper end secured -bywtbreaded engagement at 14 to an externally'threaded shoulder portion of a plunge sleeve member 15. vThe langer 'member 15' is of tubular form hav- 1n at its lower. end alsleeve extension 16 of re uceddiameter Nte'lescopieally vfitted withtion the .plunger member 1s preferably -formed'to coo eratively receive therein the usual or stan ard size valve insert or -air intake valveg17. For this' purposeit is provided with internal threadsand.. the usual 'valve seat 18. -At its upper end portion the plunger member 15 is externally threaded at- 19, the diameter and gauge of the threaded portion Vc01iforming'-to`that of the valve' sleeve extension -3 and accordingly being adapted toreceive the standard screw pump couplings vand standard size detachable valve` ca 20.

.'35 'a or the purpose'ofprovidingthe usual iiexible and sealing connectionI .between a J stationary part and the movable plungermember'in thev present construction, the upper'portion 21 ofthe securing member- 6 is 40 externally ribbed?` or serrated'and the plun ger member 15 is provided with a portion 22 similarly externally serratedv or ribbed.

A tubular rubber; sleeve 23 is fitted over the ribbedportions 21 and 22 and heldfin posxtion by the retractile coil spring 2 4 superimposed upon the sleeve to have a co mpressive securing engagement with the ortions v21 and 22A of the securing .mem ers -6 and plunger-member l'respectively. The

securing members 6 and `the l plunger member 15 are thcrebyresiliently connected and the rubber sleeve member is firmly se-A cured in position. In the construction, as disclosed, a space or clearance is provided for between the tubular extension' 16 and the inner wall of the valve sleeve 1 and likewise between the inner wall of the securing member 6 and the peripheral surface of the` tubular extension 16 thereby lallowing for o passage of the air upwardlywithin the elasxtic sleeve.23 whereby the plunger member with the attached movable indicator member 13 will be movabln `response to the nir Tn the structure 1n so far as described it avoid direct contact wit-lr in the valve sleeve 1. At its uppermostpor a t l 'ent inventlon resides' mille provision of-a 25 mounted 'accordingly will be noted that the pressure gauge'device is formed as a unitary structureadapted. for

'attachment to the valve' sleeve throughout the period of use of the inner tube to which,.

the latter-is attached. This desirable permanent use ci the detachable gauge. device 1s permitted by the desirable incorporation within' the gauge structureof the air intake valve 16 which accordinglyallows of the tire being inflated as desired through the pressure indicating device.

In the' present struc-A ture theair passing through the longitudinal bore of the plunger member 15'is conducted within the valve sleeve 1 4sous to the rubberV sleeve 23. It accordingly follows that 4in the' iniiat' ing of the tire there is no danger of foreign matter, such as oil or dust adhering to the -rubberf sleeve4 and in consequence impairing its durability and itselastic qualities.

A-further important feature of the pressignal band for indicating a range 'cipressure which it may be which may preferably be in addition to the usual graduated marking as customarily provided. Inthe illustrated' construction,

the movable indicator vided upon its outer surface with the usual desirable to maintain member 13 is prograduation and numerical marking to in- 9 dicate the pressureand readable with referenceto the upper surface of the stationary tubular indicator member 12. In addi tion thereto, provements, there isprovided a Signal upon the movable indicator member 13 and adjustable thereon. This signal band 25 is desir-ably in the. form 'of' a band of spring metal of split ringv form strung upon the tubular indicator' member 13 to have a spring grip thereon. To provide clearance' therefor the tubular indicator member" is `for a portion of its .leno'th of slightly' reduced 'diameter so as to zillowthe signal band to pass freely within the tubular stationary member 12. For

and in accordance with my'im-J band i 'determining the proper position of the sig-W nal band and its adjusted position ber 13 is provided with a serie'sotv annular4 grooves or recesses 26 and the signal band is provided on its inner surface with an. annular register with the may be readily adjusted for vindicating a. desirable range of pressure and when positioned is retained against accidental dis-. signal band is of n widthf for yieldingly securing it infj' the indicator mem-'i'l ribl or projection 27 of a size to positioning grooves. f lt follows that -lthe signal band the parts having the usual nickel iinish,'the employment of a signal band of red or magenta produces a pronouncedk and contrasting eiect which may be observed at a glance thereby to enable the operator to detmine-the approximate pressure with little .e Ort.

The outer surface `of the flange ofthe securing member 6 is? desirably knurlcd, or otherwise' specially formed to facilitate the tirhtening of the gauge ,device in its attached position. As shown in Fig. 1 -a protecting'tubular sleeve element 30 may be fitted to surround the lower ,portionof the gauge device. vThis `protective sleeve 30, as shown, being threaded` Iat its lower end upon aclamping nut 31 in turn threaded upon the usual threadsof the valve sleeve 1.
